Over the next few weeks, I'm going to TRY to accurately measure my power consumption doing daily work tasks on my big tower PC, the Steam Deck, and the HP Dev One laptop. (Using a Kill-A-Watt P3).
ALSO? Gaming power consumption comparisons between my desktop PC & the Xbox Series X, both at 4K resolution.
I expect it will be an eye-opening experience and I'll never turn on my tower again.
This will undoubtedly branch off into all kinds of software testing too. YES, I'll record & share data...
I ran some power consumption tests on #Windows 11, measuring from the wall.
My system: Ryzen 9 3900X, Radeon RX 6800 XT, 32GB RAM.
1% CPU utilization (Idle): 67W
5% CPU + 10% GPU (Streaming with Plex): 130W
Dirt 5 Benchmark (4K, High Preset, Uncapped FPS): 431W
Dirt 5 Benchmark (4K, High Preset, 60FPS Cap): 355W
Dirt 5 Benchmark (1440p, High Preset, 60FPS) Cap) : 288W
The power savings gained JUST from capping FPS to 60 is more than 2x the total power of a #SteamDeck under heavy load.
Starting #Fedora 38 power consumption tests, and decided to see how much extra power gets consumed by simply switching refresh rate from 60Hz to 120Hz (as this demands more work from the #Radeon card).
[As a refresher, it's a tower PC w/ #AMD Ryzen 3900X + Radeon RX 6800 XT]
- 1% CPU utilization (idle) @ 60Hz: 67W (this is the same result as Windows 11, btw)
- 1% CPU utlilization (idle)@ 120Hz: 97W
So an extra 30W pulled from the wall just to double my desktop refresh rate. Is it worth it?
@killyourfm
We really need a variable refresh rate. There is no point to stay at 120Hz all the time.
We could use a lower refresh rate while typing and only bump it before playing animations.
Oregon Coast Trail @killyourfm@layer8.space@Zelfir Agreed! This is something iOS and Android are already doing, right?
@killyourfm Yes but AFAIK we don't have this yet on desktop Linux environments.
